I need a 7" damper for Broan range hood that will adapt to 5" original duct or an adapter for 7" to 5" duct.
Thank you for your question on range hood ducting transitions. We do not have a transition to convert a 7" duct to a 5" duct. If the range hood requires 7" duct work, you need to stay with the 7" duct from the hood all the way to the outside. Broan does manufacture the 52,000 series range hood which does use a 5" duct size.
